Subject[PATCH 5.4 09/17] mm: unexport follow_pte_pmd
Date
From: Christoph Hellwig <hch@lst.de>

commit 7336375734d65ecc82956b59a79cf5deccce880c upstream.

Patch series "simplify follow_pte a bit".

This small series drops the not needed follow_pte_pmd exports, and
simplifies the follow_pte family of functions a bit.

This patch (of 2):

follow_pte_pmd() is only used by the DAX code, which can't be modular.
